This clock is in fact a toy, but it looks too real. (It even gets us when we handle them, and we make them!) A C4 block complete with wiring, speaker, battery & lights, activated by tilting it, sets two blinking red lights and an audible countdown alarm into action that causes extreme anxiety. If you are responsible, this is the novelty of a lifetime. If not, don't even consider this purchase. Cannot be shipped outside the Continental USA. Delivery by USPS ground service ONLY.
